SMS Sender ID Register Application

Before you apply

ACMA requires sender IDs to be connected to the organisation that uses them.

From 1 July 2026, businesses and organisations sending SMS with a text sender ID must use a sender ID registered on the ACMA SMS Sender ID Register. CloudoIP reviews each request before registration activity proceeds.

1

Confirm the organisation

Provide the legal name, trading name, ABN or non-ABN entity details, website and contact address for the organisation that owns the sender ID.

2

Prove authority

Identify the authorised applicant and provide evidence that the applicant can act for the organisation or sender ID owner.

3

Document the sender ID

Explain the sender ID, message use case, sample messages and the evidence linking the sender ID to the organisation.

Application checks

What CloudoIP will review.

The applicant is authorised to act for the organisation.
ABN, legal name, website and contact details are consistent.
Non-ABN entities have official recognition and identity verification evidence.
Entity associates have consent from the sender ID owner.
Each sender ID is linked to the organisation and is not misleading, offensive or restricted-only.
Sample messages match the stated business purpose.

Sender ID format

Use 2 to 11 characters. Do not use a sender ID that is all numbers, begins or ends with a space or underscore, uses only a restricted term, or includes "Unverified".
